Calvin and Hobbes by Bill Watterson for April 17, 1987
Calvin: I've got a scheme to get us some money. Hobbes: Oh boy. Calvin: See, I sneaked all these kernes of corn off my dinner plate tonight. Hobbes: How is that going to get us money? Calvin: Easy, I just stick them under my pillow. With any lick, they tooth fairy won't know they're fakes until it's too late!
